Lectures | 18-22 and upwards | 3 years ago | 742 viewsRating:

Metrology - the science of measurements - is responsible for the international uniformity and precision in standards. Today, the seven units for meter, kilogram, second, ampere, kelvin, mole, and candela of our international system of units (SI units....

The quantum gas is an extreme state of an ensemble of atoms when their de Broglie wave length is of the same length as the size of the container. The ways of achieving this state are described and also how its temperature is defined.

David Gross's Nobel Prize was for work on the 'strong' force which acts between quarks inside the atom. Now he works on string theory, hoping to understand how all the forces of nature could be united. He believes the next steps may involve throwing ....

K. Alexander Müller shared the Nobel Prize for Physics with J. Georg Bednorz in 1987 'for their important break-through in the discovery of superconductivity in ceramic materials'. At the age of 9 Mller was given a radio (a single vacuum tube receiv....

The idea of time travel makes great science fiction, but can it really be achieved? Paul Davies, Visiting Professor of Physics at Imperial College, describes wormholes in space and other ways that might allow travel into the past or future.

Cold Atomic Gases: the Intersection of Condensed Matter and Atomic Physics
for 18-22 and upwards,
Lectures | 18-22 and upwards | 4 years ago | 694 viewsRating:

During the past decade laser cooling and evaporative cooling of atoms have produced quantum degenerate gases both of bosons (Bose-Einstein condensates) and of fermions (gases with temperatures below the Fermi temperature). Such gases can provide ana....

For my project I am giving a brief history of color theory with emphasis on how science and color theory have interacted. I focus on aspects like primary colors, how color is perceived, and the artists who were at the forefront of color and design. I....

Most of the data we generate and receive (whether emails, tweets, videos or mobile calls) are now carried by optical fibres, which use light to transmit vast quantities of information over trans-oceanic distances. The use of hundreds of wavelengths ....

Communication on Earth, using Cables and Satellites
for 11-14 and upwards,
Lectures | 11-14 and upwards | 9 years ago | 1061 viewsRating:

A brief look at the Physics behind sending signals along cables and via geostationary satellites. An experiment to measure the speed of an electrical pulse in a cable is described and the Physics of the orbits of communcations satellites is develope....

The main problems associated with communicating with distant space probes like Voyager 1 are investigated. The role played by diffraction in limiting the amount of power receivable on Earth is discussed. The further problems of reaching a nearby st....

Lectures | 18-22 and upwards | 4 years ago | 850 viewsRating:

The founders of quantum theory assumed in 'thought experiments' that they were manipulating isolated quantum systems, obeying the counterintuitive laws which they had just discovered. Technological advances have recently turned these virtual experi....
